Nevgold Corp. (‘NevGold’ or the ‘Company’) (TSXV:NAU,OTC:NAUFF) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce the high-grade oxide gold-antimony discovery of the ‘Armory Fault’ at the Bullet Zone at its Limousine Butte Project (the ‘Project’, ‘Limo Butte’) in Nevada. The discovery of the ‘Armory Fault’ is a key, transformational development in defining the high-grade structural controls of mineralization at the evolving Bullet Zone. All drillholes at the Bullet Zone from the 2H-2025 drill program intercepted substantial oxide gold-antimony mineralization, significantly expanding the mineralization footprint at the Project. The Company continues to focus on dual track project development by advancing the near-term antimony production scenario from the historical gold leach pads at surface, while it drills the Project to define an initial gold-antimony Mineral Resource Estimate (‘MRE’).
Key Highlights
- ‘Armory Fault’ discovery identifies key structural control of high-grade mineralization at the Bullet Zone with oxide gold-antimony of 8.51 g/t AuEq* over 10.6 meters (8.11 g/t Au and 0.10% Sb), within 2.32 g/t AuEq* over 86.8 meters (1.94 g/t Au and 0.10% Sb):
-
- LB25-017 Lower Zone (step-out, new ‘Armory Fault’ discovery): 12.34 g/t AuEq* over 3.0 meters (11.95 g/t Au and 0.10% Sb) within 8.51 g/t AuEq* over 10.6 meters (8.11 g/t Au and 0.10% Sb), within 2.32 g/t AuEq* over 86.8 meters (1.94 g/t Au and 0.10% Sb); due to drilling conditions, the hole terminated in 8.25 g/t oxide Au, with the highest interval up to 12.80 g/t oxide Au
- LB25-017 Upper Zone (step-out, expansion of near-surface high-grade oxide antimony-gold): 5.46 g/t AuEq* over 3.1 meters (0.82% Sb and 2.27 g/t Au) within 3.14 g/t AuEq* over 9.2 meters (0.48% Sb and 1.27 g/t Au) within 1.59 g/t AuEq* over 21.3 meters (0.25% Sb and 0.61 g/t Au) starting at 4.6 meters; high-grade antimony is concentrated along the low-angle thrust fault under the ‘upper plate dolomite’ (Figure 2)
- LB25-016 (step-out, adds over 50 meters north of mineralization footprint): 1.25 g/t AuEq* over 10.7 meters (0.63 g/t Au and 0.16% Sb), within 0.66 g/t AuEq* over 30.5 meters (0.31 g/t Au and 0.09% Sb)
- *Gold equivalents (‘AuEq’) are based on assumed metals prices of US$3,000/oz of gold and US$40,000 per tonne of antimony, and assumed metals recoveries of 80% for gold and 75% for antimony.
- ‘Armory Fault’ is transformational to the Project as it identifies important structural controls of high-grade oxide gold-antimony mineralization (Figure 1):
- 30 holes completed in the current 2025-2026 drill program with 12 holes pending release
- Antimony is one of the highest priority Critical Minerals due to its strategic importance and military applications; Limo Butte is a brownfield mine site located in the State of Nevada with near-surface, high-grade antimony mineralization
Limo Butte Planned 2025-2026 Activities / Status Update
NevGold will continue its active exploration program at Limo Butte including:
- Evaluating the historical geological database with focus on gold and antimony (completed);
- Advancing metallurgical testwork (continuous activity);
- Continuing to drill test gold-antimony targets (30 drillholes completed, 2026 drill program will continue to test new high-grade Bullet Zone and Armory Fault discoveries, and identified project-wide targets);
- Advancing the Crushed and Run of Mine (‘ROM’) leach pads toward near-term antimony production (Phase I sampling completed, Company has engaged sonic drill contractor to drill leach pads, metallurgical testwork is continuing);
- Completing initial gold-antimony Mineral Resource Estimate (MRE) (in progress).
NevGold CEO, Brandon Bonifacio, comments: ‘The discovery of the Armory Fault at the Bullet Zone is transformational from an exploration standpoint, as it identifies what is thought to be a key structural control of high-grade oxide gold-antimony mineralization. This fault was never modelled previously, and our technical team has done a tremendous job developing this target. Our geological model testing the ‘under the upper dolomite’ target concept has been validated as we have intercepted significant gold-antimony mineralization in every single drillhole at the Bullet Zone. The mineralization footprint and upside that we have added to the future potential gold-antimony Mineral Resource Estimate (MRE) is significant, and we will start our 2026 drill program as rapidly as possible to further test this evolving, high-grade target area. We also strongly believe that this target model can be replicated project-wide, and we have many high-priority targets that are now emerging with this key transformational step-change in the project geological model. We continue to execute on all of our various work programs at Limo Butte, and the Project is one of the highest grade gold-antimony projects in the United States.‘

Limo Butte – Updated Geological Model Summary and Discovery of Bullet Zone
The Devonian Pilot Shale (‘Pilot Shale’, ‘Pilot’) is the principal local host to Carlin-type mineralization at Limousine Butte. At Limousine Butte, positive gold grades commonly coincide with silicification and jasperoid breccias within the Pilot Shale, and this alteration style is also host to elevated antimony.
NevGold’s 2021–2025 work included integrating historical drilling, new mapping, and surface sampling which produced an updated district model and refined property-wide controls on mineralization. At Resurrection Ridge, Devonian–Silurian dolomite is exposed immediately east of known gold-antimony mineralization. Earlier explorers inferred that the overlying Pilot Shale had been eroded in this area, and they did not test eastward, despite shallow high-grade intercepts in the easternmost holes drilled at Resurrection Ridge. The new model indicates the older dolomite was thrust over the prospective Pilot Shale unit (see Figure 4), creating structural preparation and a fluid trap that preserves the favorable host at depth, the classic architecture for a Carlin-type system.
The holes drilled by the Company in 2025 with assays received have continued to validate the new NevGold geological model. Holes collared in dolomite, passed through the upper thrust plate, and intersected gold and antimony at multiple horizons within the underlying Pilot Shale validating the new geological model and materially expanding the potential mineralization footprint at the Project.
The preserved Pilot Shale extends more than one kilometer east of prior drilling at Resurrection Ridge (see Figure 5).

Property-wide, the updated model outlines multiple Au–Sb target corridors that track outcrops and projected subsurface positions of the Pilot Shale, where repeated faulting and thrusting provided fluid pathways and focused mineralization. NevGold’s 2025-2026 drill program continues to test these high-priority targets.

Historical records within the project boundary document two small-scale antimony prospects—the Nevada Antimony Mine and the Lage Antimony Prospect (Figure 1). The Nevada Antimony Mine extracted stibnite (Sb₂S₃) from a hydrothermal breccia via shallow pits; the Lage prospect similarly reports limited antimony production. Complementing these records, rock-chip sampling from the Golden Butte pit (Brigham Young University thesis) returned numerous assays exceeding 1% Sb in jasperoid breccias, with several over 5% Sb, including a sample grading 9.6% Sb with visible stibnite and stibiconite (BYU Thesis Report ).
Together, these datasets support a district-scale interpretation in which thrust repetition preserves the Pilot Shale at depth east of Resurrection Ridge and focuses Au–Sb mineralization along structurally prepared horizons, establishing multiple high-priority targets for step-out drilling and follow-up work.
Importance of Antimony
Antimony is considered a ‘Critical Mineral’ by the United States based on the U.S. Geological Survey’s 2022 list (U.S.G.S. (2022)). ‘Critical Minerals’ are metals and non-metals essential to the economy and national security. Antimony is utilized in all manners of military applications, including the manufacturing of armor piercing bullets, night vision goggles, infrared sensors, precision optics, laser sighting, explosive formulations, hardened lead for bullets and shrapnel, ammunition primers, tracer ammunition, nuclear weapons and production, tritium production, flares, military clothing, and communication equipment. Other uses include technology (semi-conductors, circuit boards, electric switches, fluorescent lighting, high quality clear glass and lithium-ion batteries) and clean-energy storage.
Globally, approximately 90% of the world’s current antimony supply is produced by China, Russia, and Tajikistan. Beginning on September 15, 2024, China, which is responsible for nearly half of all global mined antimony output and dominates global refinement and processing, announced that it will restrict antimony exports. In December-2024, China explicitly restricted antimony exports to the United States citing its dual military and civilian uses, which further exacerbated global supply chain concerns. (Lv, A. and Munroe, T. (2024)) The U.S. Department of Defense (‘DOD’) has designated antimony as a ‘Critical Mineral’ due to its importance in national security, and governments are now prioritizing domestic production to mitigate supply chain disruptions. Projects exploring antimony sources in North America play a key role in addressing these challenges.
Perpetua Resources Corp. (‘Perpetua’, NASDAQ:PPTA, TSX:PPTA) has the most advanced domestic gold-antimony project in the United States. Perpetua’s project, known as Stibnite, is located in Idaho approximately 130 km northeast of NevGold’s Nutmeg Mountain and Zeus projects. Positive advancements at Stibnite including technical development and permitting has led to US$75 million in Department of Defense (‘DOD’) awards, over $1.8 billion in indicative financing from the Export Import Bank of the United States (‘US EXIM’) (see Perpetua Resources News Release from April 8, 2024) (Perpetua Resources. (2025)), and recent strategic investments of US$180 million from Agnico-Eagle Mines Limited (‘Agnico’) and US$75 million from JPMorganChase’s $1.5 trillion Security and Resiliency Initiative.
